ABSTRACT:
A gas trap having several independently controlled storage vessels (140,150). Access to each vessel is achieved via pneumatic valves (80,90), and these pneumatic valves are, in turn, controlled by solenoid valves (300, 380). The solenoid valves receive their electrical power from a relay system (520) which is controlled by a computer (550).
